l IMPROVEMENT IN STATION-INDICATORS.

Specification forming part of Letters Patent No. 179,011, dated June 20, 1876; application filed March 9, 1876.

To all whom t may concern:

Bc it known that we, A. ERNEST GOD- DARD and. JOHN I. H'rcI-IINsoN, of Essex, and GEORGE M. CLARK and SELDEN G. NORTH, of Higganum, all in the county of Middlesex and State ot' Connecticut, have invented certain new I'and useful Improvements pertaining to Station-Indicators, of which the following is a specification, reference being had to the accompanying drawings, where- 'Figure l'is a front view. view with the containing-case removed. Fig. 3 is a right-end view, (as you face the machine in Fig. 1,) with the side standard broken away. Fig. 4 is a similar view ofthe left end. Fig. 5 is a front view of the back plate and its appurtenant parts, the rollers, Src., removed. Fig. 6 is a partial central `section ot' the main roll and the appurtenant parts at its right end. Fig. 7 is an enlarged front View of the mechanism at right end of machine.

This invention is a device for use on steam or horse cars for denoting to the passengers the next station or street.l

The letter c denotes the back plate; b, the right-end standard; c, the left-end standard; d, the` length of cloth, or the like, bearing the names ofthe streets or stations in succession, and, if desired, advertisements, one to show with the name of each street or station. The letter e denotes the containing-case, having proper openings for showing the names and The letter f denotes the roll which holds the main part of the cloth at the commencement of a trip, from which the cloth runs up over the display-rolls g g, back to and around the main roll h,- from thence over the "rubber-covered pressure-roll t', and thence upon the receiving-roll pressure-roll la.

On the right end of the main roll is fastened the gear l; also, the shaft end m, on which is the sleeve n, bearing the clutch-half o and the friction-clutch half p, the latter acting in conjunction and co-operation with a correspondingiriction-cliitch hali',r, forming a part of the disk or gear l. A clutch-half, s, corresponding to the clutch-half o, is borne on the sleeve a, and is attached to the drum t. This j. We also use the clutch-half s and drum t have longitudinal Fig. 2 is a front,

play on sleeve n, to allowthe clutch-halves o and s to engage and disengage. The clutchhalt s is held toward the clutch-half o by the forked lever n and spring c. The drum t is rotated one complete revolution by a pull upon the strap fw, which is wound on the drum. The direction or' this rotation is shown by the arrow on the drum. The pull upon this strap is Vgiven by the conductor or brakeinan or driver of -the car, and the return rotation of the drum to its normal position is given by the coil-spring 1, inside the drum, fastened thereto and also to the sleeve z, which runs through the standard b.

In their normal position of rest, the two clutch-halves o and s engage, and a pull on the strap causes the main roll to make one rotation, and thereby move the cloth just far enough tol bring another street-name intosight.

The limit of rotation is given to drum by the lug al striking alternately upon the sides of the lever b1, which, for this purpose, answers as a stop.

When it is desired to roll the cloth backward, the friction-clutch halves p r are disengaged by loosening the screw c1, which runs' into the sleeve a, and bears on the shaft endy m. This disengages the main roll, so as to allow it to rotate independently of the operating devices just described-a thing that is necessary-when the cloth is to. be rolled backward or adjusted. into gear by rotating the clutch-half o, by

means of handle d1 on outer end of sleevev a,

till it meets clutch-half s, and then tightening up on screw cl.

The gear Z meshes into intermediate pinion e', and that into gear j", and so drives the roll j. The pinion c is loose on its shaft, and has longitudinal play thereon, being held in mesh by spring g', so that it can lbe pulled out of mesh with gear Z by means ot' rod h and fork t', when the main roll is to be rotated independently, or when it is to be rotated backward. As the cloth rolls upon roll j the roll increaes in size, and if it were rotated the saine part of al revolution each time it would soon call for cloth faster than the main roll is ready. to supply. The gear f is not, there- The main roll is thrownv fore, fast on shaft j', but loose thereon, having-a helical spring, k', attached to its side, bearing against collar l', which is fast on shaft j. The tension or pressure of this spring is sufcient to rotate roll i, but still leaves it free to slip when it would otherwise take up too much cloth. A peculiar brake holds roll f from unrolling by acquired momentum. It consists of a cord, mf, of leather, preferably depending from the side standard, ruiming around the roll, and having its pressure upon the roll given by spring a. Vhen the roll rotates forward the cord acts as a brake, butl movement of which in the direction indicated by the overlying arrow raises the bell-hammer u! till the end of lever t trips oli' the end of tumbler fu', and allows the hammer, under action of spring w', to strike and sound the bell y. The tumbler c' is pivoted on hammer u', pressed against pin z by spring a2, and allows lever t', on its return movement, to trip past it to position of rest. These bell-striking parts are so adjusted that the bell cannot be sounded till the main roll has been rotated just the right distance to bring a street name into display.

As to the additional brake for roll f, the letter b2 denotes it pivoted on pin c2, connected to lever p by connecting-rod d2. As this lever moves to sound the bell it applies brake b2 to roll f, and as the lever retreats the brake retreats.

We claim as our invention-fl. In combination,'rol1 h, disk l, embodying friction-clutch half r, shaft m, friction-clutch halt'p on sleeve u, and screw c1, al1 substantially as and for the purpose set forth.
